获得DDL语句的方法

获得单个表和索引DDL语句的方法

set heading off;　
set echo off;
Set pages 999;　
set long 90000;　
spool get_TABLE_ddl.sql　
select dbms_metadata.get_ddl('TABLE','TABLE_NAME'[,'SCHEMA_NAME']) from dual;
select dbms_metadata.get_ddl('INDEX','INDEX_NAME'[,'SCHEMA_NAME']) from dual;
spool off;

获得整个SCHEMA DDL语句的方法

set pagesize 0
set long 90000
set feedback off
set echo off 
spool D:\scott_schema.sql 
SELECT DBMS_METADATA.GET_DDL('TABLE',u.table_name)
      FROM USER_TABLES u;
SELECT DBMS_METADATA.GET_DDL('INDEX',u.index_name)
      FROM USER_INDEXES u;
spool off;

得到所有表空间的ddl语句

SET SERVEROUTPUT ON
SET LINESIZE 1000
SET FEEDBACK OFF
set long 999999------显示不完整
SET PAGESIZE 1000----分页
---去除storage等多余参数
SELECT DBMS_METADATA.GET_DDL('TABLESPACE', TS.tablespace_name)
FROM DBA_TABLESPACES TS;

导出oracle建表语句

set heading off
set echo off
set feedback off
spool D:\myddl.sql
select DBMS_LOB.substr(DBMS_METADATA.get_ddl('TABLE',u.TABLE_NAME)) FROM USER_TABLES U; 
spool out
set heading on
set echo on
set feedback on
